In Vivo Evaluation of Respiratory Muscles Mechanics
Respiratory muscle weakness (RMW) commonly occurs in acute or chronic illness as well as in primary neuromuscular diseases. Currently, global diagnosis of RMW is established by mouth pressure measurements during quasi-static maneuvers (Black and Hyatt, 1969, Ratnovsky et al., 1999) or imaging. Differentiation between the contributions of major muscle groups can be achieved by electromyogram (EM...
متن کاملPassive mechanics of canine internal abdominal muscles.
The internal abdominal muscles are biaxially loaded in vivo, and therefore length-tension relations along and transverse to the directions of the muscle fibers are important in understanding their mechanical properties. We hypothesized that 1) internal oblique and transversus abdominis form an internal abdominal composite muscle with altered compliance than that of either muscle individually, a...
متن کاملMechanics of the human hamstring muscles during sprinting.
PURPOSE An understanding of hamstring mechanics during sprinting is important for elucidating why these muscles are so vulnerable to acute strain-type injury. The purpose of this study was twofold: first, to quantify the biomechanical load (specifically, musculotendon strain, velocity, force, power, and work) experienced by the hamstrings across a full stride cycle; and second, to determine how...
متن کاملMyocardial mechanics in ppillary muscles of the rat and cat.
HENDERSON, A. H., D. L. BRUTSAERT, Mr. Mr. PARMLEY, AND E. H. SONNENBLICK. Myocardial mechanics in papillary muscles of the rat and cat. Am. J. Physiol. 217(5): 1273-1279. 1969.-Species differences in myocardial mechanics were studied in rat and cat papillary muscles. The intrinsic velocity of contractile element shortening (V,,,) was 3 times higher in the rat at comparable low frequencies. Res...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
